I can't unlock my N4 with the ring because of the cover I think....what do you think about the Alpha Ring? In my opinion the Alpha ring would "talk" better with the phone but I'd like to know if someone tried before buying...

Hi everybody, I received my ring 3 days ago and I'm going crazy with my
nexus4 because the nfc receiver is blocked by the cover, I think, and It
doesn't "talk" with the ring well....in the picture you can see the
location of the antenna or where I think it is...does someone have my phone
or use the some cover of mine?
